This Hornby model came with a Chinese-made 3-pole motor bogie, which gives good control and a high top speed. Overall levels of detail are ok, but the chunky pantograph could do with an upgrade. The best thing about the appearace is the headlight, which looks significantly more realistic than the plain plastic on the Class 91. I have weathered the model using dry-brushing of Railmatch paints (roof dirt and frame dirt).
